xpath

问题 I'm new to XSLT. I wonder if it is possible to select a substring of an item. I'm trying to parse an RSS feed. The description value has more text than what I want to show. I'd like to get a subtring of it based on the index of some substring. Basically, I want to show the result of a substring call passing indxOf('some_substring') and a length as parameters. Is this possible? From comments : I want to select the text of a string that is located after the occurrence of substring 回答1: It's not

问题 As per usual when making automated tests I use "Inspect"(CTRL+SHIFT+I) in Chrome to find element by xpath, id, CSS selector etc. For example: //li/a[contains(text(), "Products")] Above is an xpath from this page. In previous versions of Chrome in "DevTools"/"Elements" after pressing CTRL+F to open the "Find" option and pasting this xpath element is highlighted in DevTools window. In new version of chrome it is not highlighted, the usual "1/1" results is displayed in far right of the "Find"

问题 I'm trying to click on an element (radio button) using Selenium (in Python), I can't disclose the URL because it's a private corporate intranet, but will share the relevants part of code. So basically this element is within an iframe, thus, I've used the following code to get the element: # Select the item on main DOM that will udpate the iframe contents wait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//*[@id='sm20']"))).click() # Don't sleep, but only WedDriverWait... wait

问题 When we see conformance chart, such as https://caniuse.com/#search=xpath and https://developer.microsoft.com/en-us/microsoft-edge/platform/status/domlevel3xpath/?q=xpath, it's usually about DOM Level 3 XPath that focuses on accessing DOM object using XPath 1.0 , but not necessarily XPath 3.0 or higher. Question 1 - Is there any explicit version requirement for browsers by W3C etc. to support newer versions of XPath? This XPath 1.0 feature works: document.evaluate( 'normalize-space(" X ")',
